SAN FRANCISCO--(BUSINESS WIRE)--A retrospective analysis from ECLIPSE*, the largest safety trial of intravenous antihypertensive therapies, showed that improved perioperative blood pressure control in patients undergoing cardiac surgery is strongly associated with a reduced risk of kidney dysfunction within 30 days following the procedure.1 Perioperative hypertension – severely high blood pressure just before, during and/or after surgery – affects as many as 56 percent of cardiac surgery patients.2 The findings were presented today at the 2007 Annual Meeting of the American Society of Anesthesiologists (ASA).
